GRAIN-SHOCKER.

Specification of Letters Patent.

Patented Mar. 29, 1910.

Application filed May 21, 1908. Serial No. 434,203.

To all whom it may concern:

Be it known that I, ERNEST B. RAHNER, a citizen of the United States residing at Cazenovia, in the county of WVhodford and State of Illinois, have invented a new and useful Grain-Shocker, of which the following is a specification.

This invention has relation to grain shockers, and it consists in the novel construction and arrangement of its parts, as hereinafter shown and described.

The object of the invention is to provide a shocker in the form of an'attachment which may be applied to the frame of a binder or similar implement.

The device consists, primarily, of a wheel mounted platform provided with means for attachmentto the binder frame. Inverted U-shaped uprights are mounted upon the platform, and a track is supported at the upper portion of said uprights. A carriage is mounted for movement along the said track, and means is provided at the ends of the track for drawing the carriage along the same. A shock-holder is carried by the carriage, and, at times, is adapted to rest upon the platform, and, when in the act of dumping or depositing the shock, it moves along the track over the edge of the platform, where the shock is deposited upon the ground. The shock-holder is of peculiar arrangement, and will be explained in detail hereinafter. Means is provided for transmitting movement from one of the ground wheels of the attachment to the means located at the ends of the track for actuating the carriage. The shocker is also provided with a shock-forming device which is adapted to cooperate with the shock-holder during the process of assembling the sheaves within the same. The said former is pivotally mounted upon one of the tracks above mentioned, and, when not in use, may be swung to one side, out of the wa In the accompanying rawings:-Figure 1 is a top plan view of the shocker. Fig. 2 is an elevation of the same. Fig. 3 is an end elevation of a portion of the shocker. Figs. 4 and 5 are detailed views of a latch used upon the shocker. Fig. 6 is a sectional view of a side rail used upon the shocker. Fig. 7 is a side elevation of a portion of one of the drums used upon the shocker. Fig. 8 is a side elevation, partly in section, of a former 56 used upon the shocker. Fig. 9 is a vertical sectional view of an intermediate portion of the shocker.

The shocker consists of a platform 1, which is mounted at one side upon freely castered wheels 2 and 3. Relatively fixed supporting wheels 4 and 5 are located at the opposite sides of the platform 1. A socket 6 is mounted upon one of the side edges of the platform 1, and is adapted to receive a ball end 7 of a pin 8, which is adapted to be secured to the frame of a binder. Thus means is provided for connecting the shocker in a flexible manner with the frame of a binder. Inverted U-shaped uprights 9 are mounted upon the platform 1. Side rails 10 are supported at the upper portions of the uprights 9 and are provided with tracks or guide-Ways 11. The side rails 10 are provided with depressions 12 and 13. The said depressions are for the purpose of providing tortuous places in the track 11, the object of which will be hereinafter explained. A carriage 14 is provided at its sides with wheels 15, which operate in the tracks or guide-ways 11. A frame 16 is mounted at one end of the side rails 10, and a shaft 17 is journalecl for rotation in the frame 16. A clutch member 18 is fixed upon the shaft 17, and a clutch 19 is slidably mounted upon the said shaft. A drum 20 forms a part of the clutch member 19. The drum 20 is provided at one end with spaced flanges 21. A lever 22 is fulcrumed to a cross-piece 23 of the frame 16, and is provided with a lower forked end, which operates in the space between the flanges 21. The upper end of said lever 23 passes through the up er portion of the frame 16 and normally ies in the perforation 24,

provided in the flat spring 25 attached to the upper portion of the said frame 16. A spring 26 is attached at one end to the upper portion of the lever 22, and at its opposite end to one of the sides of the frame 16. The said spring 26 is under tension with a tendency to draw the up er free end of the lever 22 toward that side of the frame 16 with which the said spring is connected. The spring 25 is provided at its under side with a groove 27, which at times is entered by the upper end of the lever 22.

A post 28 is mounted upon the upper portion of the frame 16, and a pulley 29 is attached to the upper end of the said post. A cable 30 passes over the pulley 29, and is attached at one end to the outer or free end of the flat spring 25. The opposite end of the said cable 30 is within convenient reach of one standing upon the platform 1. One end of the cable 31 is attached to the end of the carriage, and the other end of the said cable 31 is adapted to wind upon the drum 20.

A shaft 32 is journaled for rotation at the opposite ends of the rails 10, and a clutch member 33 is fixed to the shaft 32. A clutch 34 is slidably mounted upon the shaft 32, and is provided with a drum 35. The drum 35 is provided at its end with spaced flanges 36, which operate the forked end of a lever 37, which in turn is fulcrumed upon one of the side rails 10, and has a free end 38 lying in the path of movement of the carriage 14. v

A coil spring 39 surrounds the shaft 32 and bears at one end agamst a fixed point, and

at its opposite end against one of the flanges Said spring is under 36 of the drum 35. tenslon with a tendency to normally move the drum 35 and its clutch member 34 toward the clutch member 33. A catch 40 is pivotally mounted upon one of the side rails 10, and is adapted to engage the periphery of the outer flange 36 of the drum 35, and hold the clutch member 34 out of engagement with the clutch member 33 and against the tension of the coil spring 39.

A post 41 is erected upon one of the side rails 10, and is provided with a pulley 42. A cable 43 passes over the pulley 42 and is attached at one end to the catch 40, and the opposite end of the said cable 43 is located within convenient reach of one standing upon the platform 1.

A sprocket wheel 44 is mounted upon the shaft 32, and a sprocket wheel 45 is mounted upon the shaft 17. Sprocket wheels 46 and 47 are mounted upon one of the uprights 9, and a sprocket wheel 48 is mounted concentrically with relation to the supporting wheel 4. A sprocket chain 49 passes around the wheels 48, 45 and 44, and over the sprocket wheels 46 and 47. A springactuated sprocket wheel 50 is pivotally mounted upon one of the uprights 9, and bears against the sprocket chain 49 for the purpose of taking slack out of the same. Thus it will be seen that means is provided for transmitting movement from the ground wheels 4 to the shafts 17 and 32. One end of a cable 51 is attached to the carriage 14, and the other end of the said cable 51 is adapted to wind upon the drum An arm 52 is mounted upon the end of the carriage 14, and as the carriage moves toward the shaft 17, the said arm 52 is adapted to engage the side of the lever 22 and swing the same upon its pivot, so that the said lever will disengage the clutch member 19 from the clutch member 18.

Hangers 53 are pivotally attached to the carriage 14 and are provided with upper extremities 54 having curved slots 55 which receive the cross rod 56, which in turn is attached at its ends to the sides of the frame 14. The lower ends of the hangers 53 support ashockholder. Said shockholder consists of two sections and 63, which are made up of metallic side strips 57, 58 and 59. The section 60 is fixed to the lower end portions of the hangers 53, and the other section 63 of the shock-holder is hinged to the section 60 as at 61, and is adapted to swing laterally with relation to the same. Springs 62 are attached to the outer sides of the sections 60 and 63, and are under tension with a tendency to hold the section 63 open with relation to the section 60. Strips 57 and 58 of the section 60 are provided upon their inner sides with grain-impaling tines 64, and the said sec tion 60 is provided at its lower end with parallel horizontal shock supports 65. A spring 66 is attached to the section 63, and is provided with a volute portion 67. Said spring 66 is under tension with a tendency to hold its free end toward the section 60.

A flat spring 68 is attached at its end to the section 60 of the shock-holder, and at its opposite end passes through a slot 69, provided in the intermediate strip of the hinged section 63. The said spring 68 is adapted to engage the bundles of grain when they are placed in position in the said shockholder, and has contact with the bundles substantially at the line where they are bound by the twine. A spring arm 7 O is mounted upon the section 60, and is provided at its upper free end with a plate 71', which is adapted to bear down upon the uppermost sheave of the shock and hold the same in position while the shock is be ing placed upon the ground. A rack 72 is mounted upon the section 60, and is adapted to be engaged by the arm when the same is swung down for the purpose of holding the plate 71 down in close contact with the uppermost sheave of the shock. A latch 73 is pivotally mounted upon the hinged section 63 of the shock-holder, and a keeper 74 is attached to the edge of the section 60 of the shock-holder. A shock-former is provided which coiiperates with the said shock-holder. Said shock-former consists of a crank-shaft 75, which is journaled at its upper end in a bearing 76 provided upon one of the side rails 10. Said bearing is provided with a spirally disposed slot 77, and a pin 78 is mounted upon the shaft and operates in the said slot 77. The lower portion of the shaft 75 is vertically disposed, and a sleeve 79 is slidably mounted thereon. Said sleeve is provided with blades 80. Said blades serve as bundle supports during the process of forming the shock.

From the above description it is obvious keeper 74.

elevated as it is swung to one side.

that when a shock is formed in the shockholder, the sleeve 79 and its attachments may be moved vertically along the lower portion of the shaft 75, and, when the lower edges of the said blades arrive at a point above the upper edges of the shock-holder, the said shaft 75 maybe swung laterally in the bearing 76, and, by reason of the slot and pin connection between the shaft and the bearing, the said shaft will be slightly onsequently, whenit is released it will have a tendency to swing over the shock-holder by gravity when another shock is to be formed.

The operation of the device is as follows :-As the shocker proceeds over the surface of the ground an operator standing upon the platform 1 takes the bundles of grain as they are delivered from the binder, and places them in the shock-holder. Previous to this, however, the shaft 75 has been swung, so that the shock-former carried by the shaft is rotated within the shock-holder, as above described, and the blades carried by the said shock-former serve the purpose of holding the bundles and preventing them from falling sidewise as they are stood upon end in the said shock-holder. At the same time, the spring 66 bears laterally against the bundles as they are placed in the shockholder. l/Vhen the shock has been formed the operator draws upon the cable 30, which lifts the free end of the flat spring 25, and the lever 22 swings in response to the tension of the spring 26, so that the clutch member 19 is thrown into engagement with the clutch member 18. Thus the drum 20 starts to rotate, and the cable 31 is wound thereon. This draws the carriage 14 toward the shaft 17. lVhen the wheels 15 of the carria e 14 enter the depressions 13 in the side rails 10, the said carriage will descend, and the latch 7 3 is brought in contact with an arm 81, which is attached to one of the uprights 9, and thus the said latch 73 is swung up out of engagement with the This liberates one edge of the section 63, and it is then free to swing upon its hinges 61, which it does in response to the tension of the springs 62. support is removed from one side of the shock, which has been moved over the edge of the platform 1, and as the device moves along the surface of the ground the said shock is left standing in upright position upon the same. In the meantime, the arm 52 has engaged the lever 22 and swung the same, so that the clutch member 19 is moved out of engagement with the clutch member 18, and, consequently, the drum 20 ceases to rotate. Then the lever 22 has been swung as above indicated, and its upper end comes under the opening 24: in the spring 25, the said spring 25 descends by its own resiliency and forms a means for positively Thus, the

holding the said lever 22 against the tension of the spring 26. After the shock has been deposited upon the ground, as above described, the operator draws upon the cable 43. This lifts the catch 40 and the coil spring 39 forces the drum 35 and its clutch member 31 into engagement with the clutch member 33 upon the shaft 32. Thus the drum 35 is set in rotation, and as the cable 51 winds thereon the carriage 14 is drawn toward the shaft 32 and continues in this movement until the wheels 15 enter the depressions 12 in the side rails 10. At the same time that this happens the end of the carriage 14 comes in contact with the free end 38 of the lever 37 and the said lever is swung upon its fulcrum, so that the drum 35, and its clutch member 34 is moved away from the clutch member 33 and against the tension of the spring 39 and under the catch 40, which, by gravlty, engages one of the flanges 36 and holds the parts in the last said position. By reason of the fact that the upper portions of the hangers 53 are pivotally connected with the carriage 14, the said hangers may have a limited swing, which will facilitate the depositing of the shock on the surface of the ground. Also, when the carriage 1 1 is moved toward the shaft 32 the said wheels 15 thereof pass into the track depressions 12, and the lower end of the shock-holder will rest flat upon the platform 1. In its initial movement toward the shaft 17 the shock-holder is first lifted, and then the shock is moved over the edge of the platform and deposited upon the ground as above described. The sprin 66 brushes against the side of the shock, and when the shock is in. position upon the ground it is moved away from the same by the onward movement of the shocker.
